Abstract

A unique method of embedding an RFID chip into the core of a golf ball and using it in the application of a limited flight range ball for use in a range setup that can receive and monitor RFID signals is disclosed herein. The density of the core material is adjusted in relation to the mass of the RFID chip. The golf ball with an embedded RFID chip conforms to a mass limitation of the USGA.

First claim

We claim as our invention the following:

1. A method for manufacturing a limited flight golf ball with an embedded RFID chip, the method comprising:
placing a first half-slug of core material in a mold half;
placing a RFID chip on a surface of the first half-slug;
placing the second half slug on the RFID chip;
molding the first half-slug, the RFID chip and the second half slug using a hot cure compression process to form a golf ball core with an embedded RFID chip;
molding a cover over the golf ball core to generate a golf ball with an embedded RFID chip;
wherein the density of the core material is adjusted in relation to the mass of the RFID chip;
wherein the golf ball has a COR less than 0.770 and a mass less than 43.0 grams;
wherein the golf ball with an embedded RFID chip has a mass no greater than 45.93 grams;
wherein the golf ball has a lift of 0.1047 at a Reynolds number of 70000 and a RPM of 2125, a lift of 0.2079 at a Reynolds number of 80000 and a RPM of 2125, a drag of 0.2322 at a Reynolds number of 170000 and a RPM of 2125, a drag of 0.2326 at a Reynolds number of 200000 and a RPM of 2125, and a drag of 0.2361 at a Reynolds number of 225000 and a RPM of 2125.

2. The method according to claim 1 wherein the cover has a Shore D hardness of 61, a thickness of 0.061 inch and is composed of ionomers.

3. The method according to claim 1 wherein the golf ball has 336 dimples, wherein each dimple has a radius of 0.076 inch, a chord depth of 0.012 inch, an entry angle of nineteen degrees and an edge radius of 0.04 inch.

4. A method for manufacturing a limited flight golf ball with an embedded RFID chip, the method comprising:
placing a first half-slug of core material in a mold half;
placing a RFID chip on a surface of the first half-slug;
placing the second half slug on the RFID chip;
molding the first half-slug, the RFID chip and the second half slug using a hot cure compression process to form a golf ball core with an embedded RFID chip;
molding a cover over the golf ball core to generate a golf ball with an embedded RFID chip;
wherein the density of the core material is adjusted in relation to the mass of the RFID chip;
wherein the golf ball has a COR less than 0.770 and a mass less than 43.0 grams;
wherein the golf ball with an embedded RFID chip has a mass no greater than 45.93 grams;
wherein the core has a diameter of 1.56 inches, a mass of 37.8 grams and a deflection of 0.094 inch under a load of 200 pounds.

5. A method for manufacturing a limited flight golf ball with an embedded RFID chip, the method comprising:
placing a first half-slug of core material in a mold half;
placing a RFID chip on a surface of the first half-slug;
placing the second half slug on the RFID chip;
molding the first half-slug, the RFID chip and the second half slug using a hot cure compression process to form a golf ball core with an embedded RFID chip;
molding a cover over the golf ball core to generate a golf ball with an embedded RFID chip;
wherein the density of the core material is adjusted in relation to the mass of the RFID chip;
wherein the golf ball has a COR less than 0.770 and a mass less than 43.0 grams;
wherein the golf ball with an embedded RFID chip has a mass no greater than 45.93 grams;

wherein the golf ball has a deflection of 0.080 inch under a load of 200 pounds.
